HOUSING F'ORI ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 522,641, dated July 10,1894.

Application filed July 27,1893; Serial No. 481,676. (No model.)

To all whom it may concern.- Y

Be it known that I, SAMUEL T. WILLIAMS,

of Muscatine, Muscatine county, Iowa, have invented kcertain new anduseful Improvements in Rolling-Mill Housings, of which thev following isa specification. v

This invention pertains to improvements in housings for rolling-millsand relates to the means for carrying and holdingdown the rolls,

for adjusting the roll-boxes lengthwise of the rolls, and for protectingthe lower screw.

My improvements will be readily understood from the followingdescription taken in connection with the accompanying drawings, inwhich`v Figure 1, is an elevation of the inner face of arollin g-millhousing vexernplifying my improvements, portions appearing in verticalsection in the plane of line c of Figs. 2 and 3; Fig. 2, a sectionalplan of the same in the plane of line a of Fig. 1: and Fig. 3, a sectionin theplane of line b of Fig. 1,viewed upwardly.

In the drawings:1, indicates the housing proper, whose general form isas usual: 2, the lower roll-box: 3, the intermediate roll-box: 4,'strap/for the intermediate roll-box: 5, top roll-A box: 6, strap for'thetop roll-box: 7, top screw: 8, holes through the cheeks ofthe housing,

extending from the inner faces of the hous-` in g-cheeks, at about thelevel of strap 6, diago. nally upward: 9,bolts extending through theholes 8 and having adjusting nuts upon theirV upper ends: 10, T-shapedheads upon the lower ends of bolts 9,'these heads bearing against theinner faces of thehousing cheeks and coming up against the undersurface` of strap 6, the holes for the bolts 9 being enlarged at theirlower ends so as to permit the bolts to swing: 11, holes through thehousing cheeks, extending from about the level of strap Il diagonallydownward: 12, bolts disposed in these holes and having adjusting nuts ontheir lower ends, the upper ends of the bolts projecting through thewings of strap 4: 13, cotters through bolts 12 over the strap 4: 14:,holes through the roll-boxes horizontally, near to and parallel with theinner faces of the housing cheeks: 15, hook=bolts in these holes in'theboxes, the hooks engaging the inner face of the housing and the otherend of the bolt'slhaving adjusting nuts i coming against the outer faceof the boxes:

16, rabbets upon the inner corners of the housing-cheeks, thehook-'bolts 15 engaging the housings at these rabbets: 17, the lowerscrew ofthe housing: 18, the usual gear thereon:

. 19, a vertical hole in the base of the housing,

concentric with screw 17, and larger than the screw, and counterbored atits upper end: 20,

onto the screw 17 and having its lower end Y. fitting the counterbore inthe housing'and the upper end of screw 17 and having its bore engagingthe upper end of the screw-box, the roof'of this cap being pinchedbetween box 2 and the upper end of the screw: and 22, a

thimble surrounding the lower portion of the screw, below the screw-box,and projecting up into the hole 19.

I`Bolts 12 serve in drawing down the strap 4 upon the journal of theintermediate roll. The removal of cotters 13 permits of the readyremoval of these bolts and of the strap.

Bolts 9 serve in supporting strap 6 and in thus carrying the top rolland the nuts upon these bolts permit of easy and delicate adjustment.Hook-bolts 15 serve in adjusting the'roll-boxes in the housings endwiseof the rolls and thus serve in delicately adjusting the rolls endwise.These hook bolts are easily removed, as are also the roll-boxes.

Cap 21 serves in protecting the upwardly projecting portion of the,lower screw from the dirt to which it is exposed at this point. Thimble22 protects the lower portion of this Screw.

I claim as my invention- 1. In a rolling-mill housing, the combiuaing,and the rollboxes and straps mounted toslide and be guided verticallytherein, of

`6o the screw-box for the lower screw, threaded bolts passing diagonallythrough the cheeks of the housing and engaging with their inner upperends over one of the straps and provided atv their lower ends withadjusting nuts, and serving to prevent the rising of such strap in itsguide in the housing.

3. In a rolling-mill housing, the combination, substantially as setforth, with the housing, and the roll-boxes and straps mounted to slideand be guided vertically therein, of bolts disposed diagonally throughthe cheeks of the housing and through one of said straps and havingadjusting nuts on their outer lower ends, and cotters through the innerupper ends of said bolts over one of said straps.

4. In a rolling-mill housing, the combina tion, substantially as setforth, with the heusing and roll-boxes mounted therein, of hookboltspassing horizontally through the rollboxes and having their hooksengaging one face of the housing and provided upon their other cndswithadjusting nuts seating against the roll-boxes.

5. In a rolling-mill housing, the combination, substantially as setforth, with the housing and the roll-boxes mounted therein, of a screwmounted in the housing under the lower roll-box, a cap surrounding theupper end of the screw and having its roof pinched between the screw andthe lower roll-box, and a boss or hub mounted in the housing concentricwith the screw and projecting up into screw.

7. The combination, substantially as set forth, of a rolling-millhousing provided in its base with a hole counterbored at its upper end,a screw-box seated in said counterbore and projecting upwardlytherefrom, a screw threaded into the screw-box and projecting upwardlythrough the same, and a cap disposed over the upper end of the screw andhaving its wall encircling the upwardly projecting portionof thescrew-box.
